ACETYLENE-GENERATOR.

. Specification of Letters Patent.'

Patented Nov. 29,

Application filed June 18, 1920. 'Serial No. 389,933.

To all whom it may 00mm Be it known that I, JAtrns NV. GAIN, a citizen of the United States residing at Detroit,

in the county of l/Vayne and State of Michigan, have invented a new and useful AcetyleneGenerator, of which the following is a specification. I a

This invention-has reference to lamp constructions, and more particularly to lamps especially adapted for use as miner lamps.

The primary object of the invention is to provide a lamp of the carbid burning type, wherein novel means is provided for insuring a true adjustment of thewater regulating means to lnsure a constant discharge of the water from the water containing receptacle to the carbid containing receptacle, disposed thereunder.

A further object of the invention is to pro 1' vide means for connecting the water receptacle and carbid receptacle, whereby the same may be readily and easily disassembled to facilitate the cleaning of the carbid to insure the efficient operation of the lamp.

A still further object of the invention is i to provide a combined burner and reflector,

Figure 1 illustrates a longitudinal sec-- tional view through a lamp constructed in accordance with the present invention.

Fig. 2 is a transverse sectional view taken on line 22 of F 1g. 1.

Fig. 3 is an elevational view of the burner and reflector.

Referring to the drawing in detail, the reference character 5 designates the base or lower receptacle of the lamp, which supports the carbid, employed in thistype of lamp for generating the gas. The upper portion of this base 5, is threaded as at 6 to accommodate the threaded portion 7 of the top ofthe lower receptacle 5, whlch is indicated by the reference character 8 and which has a f forwardly extending portion 9,*that-sup-'- ports the'burnen- The water containing receptacle 10, which is supported by {the lower receptacle 5, is substantially funnel shaped, having the tapered portion 11 thereof fitted within a suitable opening provided in the top 8, the downwardly extending flanges 12, forming the walls of said opening providing rests for the water containing receptacle 10, and towhich flanges the water containing receptacle 10 is secured in any suitable manner.

- The feed end of the water containing receptacle 10'is open as at 13,'the walls of the opening-being curved slightly inwardly as at 14,.so, that the walls overlie the nut 15,

which is positioned within'thetube 16 and supported adjacent to the feed end ofthe 'water containing receptacle and frictionally held in spaced relation therewith, to provide a water passageway between the lower end of the water containing receptacle, and the nut 15 Secured to the feed end of the water containing receptacle 10, is a discharge tube 16 I a which has its upperportion fitted over the feed end of the'water containing receptacle, and secured thereto in any. suitable manner, the lower portion of the discharge tube 16 being tapered toward the free end thereof to provide a seat for the valve member 17, which'has its lower extremity disposed within'the open end of the discharge tube 16 in a manner. to close the .discharge tube, or

regulate the size of the opening at the bottom thereof, to Vary thequ'antity of water fed to the carbid containing receptacle 5.

' In orderthat an adjustment of the valve member 17 may be had, the valve member is provided withthe exterior threads 18, which are received by the internal threads of the nut 15, so that movement of the valve mem her will cause the lower extremities thereof to be adjusted with relation to the walls of the opening in which the same is disposed It might be further stated that the nutv 15 is provided with openings 19 disposed in suitablesp-aced relation with'each other,

which openings permit the passage of water from the water containing receptacle 10, to the receptacle 5, disposed thereunder.

Forming an important feature of the present invention, is the combined reflector and burner indicated at 20, the reflector having the usual flared reflecting surface, while the inner portion thereof is formed into a burner tip 21, the portion adjacent the burner tip being threaded as at 22 to permit the same to be positioned within the forwardly extending portion 9 of the top of the carbid containing receptacle 5.

A cover 23 is positioned on the water receptacle 10, which cover is provided with an 1 auxiliary cover 24 to permit water to be positioned within the receptacle 10 and eliminating the necessity of removing the cover 23. Secured to the, rear of the lamp, is a supporting bracket 25, which may be of any desired construction, to permit the same to besecured to a miners hat, or like supporting device.

In the operation of the device, a quantity.

of carbid is placed in the carbid containing receptacle 5, and a quantity of water is placed in the water containing receptacle 10. The rod member 17 18 now adjusted to a predetermined position, to permit the water to discharge into the carbid containing receptacle 5, whereupon gas is formed in the usual manner, which gas passes to the burner 21, through the opening 26formed in the front wall of the top member of the carbid 7 containing receptacle 5. It is obvious that by applying a match to the burner 21, the

water containing receptacle being formed into a funnel-shaped downward extension terminating wlthln the discharge tube in a restricted mouth, a nut frictionally held within the-discharge tube and in spaced re lation below the restrlcted n1outh,sa1d nut having openings to permit fluid to pass therethrough, and "a threaded valve member operating through a threaded opening in the nut for controlling the passage of fluid through the discharge tube.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses. v
